General Election 2010: Half of voters might change their minds before polling day

7.44PM: Fascinating Ipsos-Mori poll out today.

It says: 'Half the public (49%) say they may change their mind about who to vote for, it's highest level since we started asking this in 1983.'

And turnout looks likely to be up. The percentage of those who say they are certain to vote has increased, by 11 percentage points, to 64%.

It also finds that 'in terms of party identification, a fifth (21%) generally think of themselves as Liberal Democrats. This is a six percentage point increase since February. More still identify with the Conservative party (28%) and the Labour Party (31%).'
